Australian and New Zealand standards mandate testing of fault loop impedance on circuits not protected by RCD's, both at installation and after maintenance. The CZ20054 Loop Impedance Tester conducts earth fault loop impedance and prospective short circuit current (PSC) tests.

Detection impedance is the importance unit to detect the discharge information from discharge testing loop, also known as input unit. There are two kinds of detection impedance, ordinary detection impedance and capacitive divider detection impedance, capacitive divider one can test voltage and zero mark position without connecting to external divider.

High Current Load Cycle Test Systems are designed to raise and control the temperature of a conductor or other low impedance electrical loops. This process will simulate the current loading conditions found in electrical circuits. The heating is achieved by utilizing the test loop as the secondary winding of a current transformer for inductive heating. Measurement of the loop temperature is made by direct contact of a K type thermocouple probe with the conductor of the test loop. Various systems are offered as low voltage or higher voltage test systems.

The HCTS Series Cable Heat Cycle Test System is designed to raise and control the temperature of conductor or other low impedance electrical loop to simulate the current loading conditions found in the electrical circuits up to 10000A.

The patented RAPID load-pull concept employs the latest in PXI test instrumentation. The technique employs a ‘quasi closed loop’ approach, this approach maintains the speed of a closed loop active load-pull system but removes the inherent stability issues that limit their application. Here the output signal from the device is fed to a circulator, and passed to the PXI chassis where the signal is down-converted, modified to set the desired impedance, unconverted and then injected back to test device to set an invariant impedance. As there is feedback any change in the device output, such as a change in drive level, this is automatically compensated for in the feedback signal. The result is extremely fast impedance changes and a super fast calibration process.

It can be used to test insulation resistance, continuity, loop impedance and RCCB, earth resistance tester, five major test requirement in the electrical testing industry. Phase indicator. Can check a wide range of 3-Phase Power source from 110V to 600V

Multi-channel impedance line failure analysis system MIR1101 mainly used for online measurement impedance variation becomes an incubator PCBA / PCA, and can visually show the impedance of each loop on the PCBA / PCA with temperature trends. From these data, you can quickly determine PCBA / PCA circuit failure and failure temperature cycle and temperature values ​​at failure, and can do further analysis of the reasons for the failure on this basis. As an impedance failure analysis complete solution, MIR1101 addition to having the advantages of a long, multi-channel, online testing, offline playback, but also can greatly save your test fee. LXI and VXI architecture which can be more reasonable to optimize your equipment investment.
